My office PC is now a Linux (Fedora) because of the Windows10 pricacy issues. I started with Ubuntu, cut they like to know about you as well, so I shifted to Fedora. If its good enough for Linus Thorvald, then it should be OK for me as well.
My gateway is a Cisco Sourcefire box, so I have a complete log of any traffic and where it goes.
Most of the small programs I use, I go through the sourcecode before compiling it.
But I still have two Windows8.1 boxes - one for videoediting and one gaming PC that havent been used the last 6 months
Google and Facebook still knows way to much about me, but at least I can keep out of the search bubble
